gsm48_tx_release_compl(): Don't use transaction after trans_free()

In commit 39e2eadc99c38876c39700cc2f8fa2a2973c1fdd a bug was introduced
that used the 'trans' after trans_free() had already been called.

This became visible now when the openbsc+lcr combination was calling
an unknown/invalid telephone number in a MO call, resulting in
a segfault.
